This invention relates to supports, and in particular to adaptation supports for vehiclemounted machines, such as pumps, compressors and other machines driven from a power take-off on the vehicle. 1

One objectof this invention is to provide an attachment device for mounting machines driven from a power take-off on the vehicle wherein the device is quickly attached to and detached from the vehicle So that it is mounted on the vehicle only when necessity for its use arises and at other times it is stored away from the vehicle.

Another object is to provide an attachment device for machines mounted on vehicles .and drivenv from a power take-ofi' thereon wherein the device includes a support mounted on the draw bar mechanism of the vehicle, such as a tractor, land is simply and quickly removable therefrom.

Another object is to provide an attachment device as set forth in the lpreceding objects wherein a simple adjustment is provided for taking up slack in the belt byL-Which the machine is driven-from'thepower take-ofi,v i

Other objects and advantages ofthe invention will become apparent during the course of the following description of the accompanying drawings, wherein: 1 f

Figure 1 is a side elevation of an attachment device, according 'to one form of this invention as applied to the draw bar mechanism of a conventional farm tractor;

Figure 2 is a rear elevation of a portion of the tractor andv attachment device shown in Figure 6; and

Figure 3 is a vertical section through the belttightening mechanism forming a part of the` attachment device of this invention.

Referring to thedrawings in detail, Figures 1 and 2 show the rearward portion of a conventional' type of tractor, generally designated |05, well-known in farming and industry upon which is to be temporarily and removably mounted a machine, generally designated |02, which is to be driven from the power take-off shaft of the tractor, as described below.

The machine |02 to be driven from the power take-01T output shaft of the tractor |05 may be pump, compressor or other desired type-of machine, depending upon the use to which it is to be put. For purposes of illustration, the machine f |02 is shown as a pump having a casing 58 with inlet and outlet connections 59 and 00 and an access plug v6| threaded into anopening therein. The machine |02 `is provided with a shaft outrigger bracket 52 bolted asat 63 to the casing 58 and serving torotatably support the machine shaft 69, the opposite end of which is journaled in the housing 58.- Y- -v In order to drive the machine |02, an adjustable driven pulley, generally designated 11, is

mounted upon the machine shaft 69. For this purpose (Figure 3), the machine shaft 69 is provided with a reduced diameter portion 18 having a keyway 19 to which is keyed the hub 80 of a hollow cylindrical member 8| having a fixed pulley side wall 82 integral therewith.l Thehub 80fis additionally heldin position by a nut or cap screw 80a threadedupon or into the vouter end of the reduceddiameter Shaft portion 18. Slidably and rotatablyV mounted upon the'outer surface 83 of the cylindrical Amember 8| is a sleeve portion 84 having an adjustable pulley wall 85 integral therewith at the end thereof facing the pulley wall 82. The cylindrical member 8| is provided with peripherally spaced threaded holes 85 into which are threaded cap screws 81, the Shanks ofwhich pass through'spiral orinclined slots 88, washers 89 being provided between the heads of the cap screws 81 and the sleeve member 84.

In order to temporarily and removably'support the machine |02 upon the tractor |05, according to one form of the invention, Figures` 1 and 2 show an attachment device, generally designated |00 consisting of an attachment support, generally designated |0| upon which is mounted the machine, generally designated |02 operated by driving mechanism, generally designated |03l and equipped with adjustable bracing means, generally designated |04. The attachment devicel00 is mounted upon a farm tractor, generally designated |05, the rearward portion of which includes wheels |05 and tires |01 rotatablymounted upon an axle |08 within a rear axle housing |09 and driven from the engine and transmission mechanism (not shown) of the 4tractor |05. The rear'axle housing |09 is provided with an extension 0 (Figure 1) upon the upper portion thereof and having a seat bracket bolted thereto as at H2 and carrying an operators seat `ll3. The rear axle housing |09 is also provided Vwith an upwardly extending integral support I4 having a bore I5 therethrough pivotally supporting a pivot pin IIB `which in turn pivotally supports the lower arms of bell cranks H8, the upper arms I9 of'which are bored at their intersections to receive a pivot pin |20. Connected to the pivot pin |20 is a yoke |2| mounted upon the end of a plunger shaft |22, the intermediate portion of which passes through a bore |23r in a wall |24 of the housing extension ||0 andV on opposite sides of this wall is provided with compression coil springs |25 and |20 respectively. The coil spring |25 abuts at itsiforward end against the yoke` |2| and'at itsfrearward'end against the wall |24, whereas the coil spring^|26 abuts at its forward end againstthe wall |24 and atlits rearward end vagainst a washer |21 held in position byV a nut |23 threaded upon the rearward end of the plunger shaft |22. The for- Ward ends of the upper arms l 9 of the bell crank are bored to receive a pivot pin |29 which in the normal use of the tractor serves to support the draw bar or other towing or pulling device (not shown) employed with the tractor. This is removed in order to mount the attachment device |00 and in its place is mounted the attachment support The latter consists of a platform |30 supported upon an integra-l depending arm |3| forming a pivot support and bored as at |32 to receive the pivot pin |29. Bolted as at |34 to the platform |30 is the machine |02. The machine |02 is also driven by the adjustable pulley 71 previously described.

The rear wall of the housing 50 of the machine |02 is provided with a projecting ear |35 carrying a pivot bolt |38 to which is connected the upper threaded member |31 of the bracing means |04 which is in the form of a turnbuckle having a threaded adjusting member |38 threaded upon the adjacent ends of the upper threaded member |31 and lower threaded member |3'Ia. The lower end of the latter is pivotally mounted upon a pivot pin |39 carried by the bracket |40 secured by the same bolts ||2 which secure the seat bracket to the rear axle housing extension H0.

The tractor |05 is provided with a power takeoff shaft |4| mounted in a lower rear axle housing extension |42 and journaled in the closure plate |43 bolted thereto as at I 44 (Figure 1). The outer end of the .power take-off shaft |4| is splined as at |45 for the reception of gears, pulleys or the like for driving external machinery. The driving mechanism |03 includes a drive pulley |46 having an internally splined hub |41 mounted upon the spline |45 of the power take-olf shaft |4| and secured thereto by the set screw |48.Y The drive pulley |46 and the adjustable pulley 'Il are drivingly interconnected by an endless belt |49 threaded around their respective peripheries.

In the installation of the attachment device |00 shown in Figures 1 and 2, the platform |30 is mounted upon the pivot .pin |29 in the manner previously described, and the machine |02 secured thereto by the bolts |34. The bracket |40 is per- -nianently attached by removing the bolts l2 and reinserting them after placing the bracket |40 beneath them (Figure l). The pulley mounted upon the power take-off shaft |4| and secured in position by the set screw |48. With the machine |02 tilted forward, the endless belt 49 is mounted upon the grooved periphery of the pulleys |46 and |41, whereupon the machine |02 is swung to an upright position around the pivot pin |20. The bracing means or turnbuckle |04 which has been previously connected at its upper end to the pivot bolt |35 is now secured at its lower end to the pivot pin |39 whereupon the adjustment member |38 is tightened in order to bring the machine shaft B9 and power take-off shaft 14| into parallelism, the adjustable .pulley l1 being adjusted in the manner previously described to impart the propert tightness to the belt |49.

In this form of the invention, the machine |02 may be removed from the vehicle by reversing the operations described above in connection with the installation and operation thereof in an obvious manner. Y

While I have shown and described my invention in detail, it is to be understood that the same is to be limited only by the appended claims, for

` said machine, and an endless nexible driving member drivingly interconnecting said pulleys.
